Lisa Dobriskey, one of Britain's medal stars from Berlin, has revealed that she might swap distances instead of defending her Commonwealth 1500m crown next year.

Dobriskey has had the week of her athletics life - winning 1500m silver at the World Championships and then smashing her personal best time at the Golden League in Zurich on Friday night.

But the middle-distance heroine may drop to the 800m in 2010 to keep herself fresh on the long road to the London Olympics.

There are two major Championships next year - the European in Barcelona in July and the Commonwealth in New Delhi in October. The 25-year-old shot to fame when she won the Commonwealth 1500m in Melbourne in 2006, but now may run the 800m in India.

Dobriskey is coached by George Gandy - who guided double Olympic 1500m champion Sebastian Coe in his early days. She said: "We are going to look at different possibilities in terms of doing a different event in one or the same event.

"We were thinking maybe an 800m could be a possibility, but we would have to see how things go.

"It is so competitive, and would I get in the team? I've got decisions to make."

Next stop is Gateshead tomorrow where she'll be one of 32 medallists from Berlin competing at the Aviva British Grand Prix.
